BuiT, Note on tlie Classification of tlie Dermaptera. 325 



Subfamily 4. Pyragrin a e. 

 This group , with Pyragra Serv. , EcMnopsalis Borm. , Pyra- 

 gropsis Bor., Echinosoma Servr. and Arthroderus Caudell, has certain 

 affinities with the Pygidicraninae , but in my opinion, the balance 

 is in favour of their inclusion in the Labiduridae. In the form 

 of the feet and organs of flight and above all, of the pygidium, 

 they agree Avith the Labiduridae. 



Subfamily 5 . Labidurinae. 

 For Labidura, Forcipida and Tomopygia and also for Demogorgon 

 Kirby , if that genus be proved to be good. Its chief character, 

 absence of wings, is insufficient to justify generic rank. 



Subfamily 6. Psalina e. 



This includes several genera which are all closely related to 

 each other, namely Gonolabis Burr (nee VerhoefP), Anisolabis Fieb. 

 find Psalis i) Serv. The latter only differs from Anisolabis in its 

 well developed organs of flight. Carcinophora Scudd. , seems to 

 coincide with Psalis. 



The exact position of Labidurodes is doubtful. It probably 

 comes here. 



A new genus is required for Anisolabis colossea Dohrn with 

 lobed mesternum , and also for those species of Anisolabis which 

 have rudimentary elytra. For the latter I now propose the name 

 Borellia n. g. , for those species of Anisolabis which have rudi- 

 mentary elytra ; these are not generally contiguous at any point 

 and are usually soldered to the pronotum. It affords me great 

 j)leasure to dedicate this genus to my good friend Dr. Alfredo 

 Borelli, whose numerous works on the Dermaptera-Fauna of Africa 

 and South America constitute a very valuable addition to our 

 knowledge of the group. 



Anisolabis moesta Gene, may be taken as the type of this new' 

 genus which will also include the following species : A. ambigua 

 Borelli (C. America) , A. janeirensis Dohrn (Brazil) , A. andreinii 

 Bor. (Eritrea), A. greeni Burr (Ceylon), A. peruviana Borm. (Peru), 

 A. armata Borelli (C. America) , A. tasmanica Borm. (Australasia), 

 A. stall Dohrn (Oriental) and A. annandalei Burr (India) , but not 

 A. cincticollis Gerst., which is a Psalis. 



Family 5. Forficulidae. 



This family was revised by me a few years ago (Tr. ent. 

 Soc. London, 1907, p. 91) but the forms are so numerous and 



1) Psalis indica Hagenb. , its allies is removed to AUostetJms
